BiasAddBackprop¶
Versioned name: BiasAddBackprop-1
Category: Arithmetic
Short description: Computes the gradients on the “bias” tensor for add bias operator.
Detailed description:
This op accumulates all the values from output_delta into the channel dimension, the axis depends on the layout of input tensor.
Inputs:
1:
output_delta- gradients tensor w.r.t. the output. Required.
Attributes:
data_format
Description: data_format denotes the data format of the input.
Range of values: NXC or NCX (X means HW for 2D, DHW for 3D)
Type: string
Default value: NXC
Required: no
Outputs:
1:
bias_delta- gradient tensor w.r.t. bias.
